Abstract : In this research, human subjects repeatedly endured prolonged high-G simulated aerial combat to the point of loss of vision or physical exhaustion. Some profiles included over twenty plateaus at 9 Gz. Measures of cognitive and neuromuscular function, mental workload, and physiologic status were taken throughout the exposures, as well as neuropsychologic examinations after the exposures. Results indicate that more advanced protective systems not only allow longer endurance, but provide adequate support for maintained cognitive performance throughout the extended exposure. Although measures were affected by the type of protective system the subject was wearing as well as individual ability and coping strategies, consistent target tracking task performance, rapid recall decision reaction scores, and sufficient arterial oxygen saturation were maintained throughout extended exposures to a point preceding termination by only a second or two. No neuropsychological decrement was demonstrated post exposure.
